| Each time
an indexing source like a search engine or online
directory service is asked to review and include your web
site’s contents within it's listings, it sends out
user agents to analyze every aspect of your web site. (
search engine robots and spiders )
These agents are often referred to as "spiders",
"bots", and "crawlers". While
many may argue that these agents have different names for
specific reasons, it truly matters on where they come from.
But, their basic function is always the same.
Spiders, Bots, and Crawlers are defined as:
Computer applications that travel Internet's various resources
in search of web sites for it's host database to list and
offer to information seekers. This type of program reads
and copies text and other sources of informative content
from your site, then assigns that particular URL, or page,
a ranking based upon relevancy of certain keywords, phrases,
and subject matters. These automated applications are preprogrammed
to review page construction and coding to then add (or remove)
that page to a database based on it's rank achieved.
Upon their initial visit to your web site,
these agents will start at your web sites front door or
index page and begin looking for where it can go from there.
Following text links, these applications are able to compose
a map of your entire web site and it's linked contents.
Once this map of your site has been created, it can begin
analyzing your various pages contents and look for what
information is offered.
Using the map as a guide, these bots and
spiders begin crawling every resource that it knows is available.
Focusing on the text, alt tag attributes, and links of each
page, a running record of all of the information is retained
for further analysis. When the bot has analyzed and recorded
a page in its entirety, it will then search through it's
findings looking for words, phrases, and themes that are
repeated in the page's contents.
A rank is then assigned to each page based
upon the criteria that these automated applications are
programmed to look for. This is what is referred to as the
search engines algorithm. For a more complete understanding
of how page rankings are composed and used, please review
